Evaluating Pomegranate Cultivars for Resistance to Anthracnose Fruit Rot, a Severe Fungal Disease in Florida and Southeast United States

EP643/ENH1379by Alexander Schaller, Zhanao Deng, Gary E. Vallad, and John M. ChaterMarch 5, 2024Pomegranate (Punica granatum L.) has primarily been cultivated at home in Florida and other southeastern states. Over the past 15 years, growers, nurseries, researchers, and Extension agents have explored the potential of pomegranate as an alternative fruit crop. Early field trials revealed that pomegranates are highly susceptible to Colletotrichum gloeosporioides, causing severe anthracnose fruit rot and premature fruit drop. The development and use of disease-resistant cultivars are considered some of the best methods to manage this disease. This publication presents our findings from evaluating 35 pomegranate cultivars under natural disease pressure in central Florida and by artificial inoculation. The susceptibility of such pomegranate cultivars varied widely, with six exhibiting resistance to anthracnose fruit rot. More comprehensive research is warranted to further develop anthracnose-resistant cultivars and to enhance our understanding of disease resistance in this crop. Critical Issue: 1.

New Caladium Cultivars ‘Dots Delight’ and ‘Wonderland’

EP641/ENH1377by Zhanao Deng and Natalia A. PeresDecember 22, 2023Caladiums are ornamental aroids valued for their vibrant and morphologically diverse foliage. Grower surveys indicated that they planted more acres of lance-leaved cultivars in recent decades to accommodate rising consumer demand. The caladium breeding program at the UF/IFAS Gulf Coast Research and Education Center has been developing new lance-leaved cultivars that can produce attractive, robust plants with many bright, colorful leaves and improved tuber yield potential. The program has recently released two new lance-leaved cultivars. ‘Dots Delight’ is well suited for use in sunny landscapes, having excellent tolerance to sunburn and strong resistance to the leaf spot disease. Though they may need one to two additional weeks to produce potted plants, tuber yield potential is intermediate to high. ‘Wonderland’ is well suited for potted plant production in sunny or shady landscapes or gardens and has showed good leaf color display, sunburn tolerance, and leaf health.Critical Issue: 1.

Homeowner Best Management Practices for the Home Lawn

EP236/ENH979 by Alex J. Lindsey, Marco Schiavon, J. Bryan Unruh, and Laurie E. TrenholmDecember 12, 2023A healthy lawn is an important component of an urban landscape. Not only do lawns increase the value of a property, but they also reduce soil erosion, filter stormwater runoff, cool the air, and reduce glare and noise. A healthy lawn effectively filters and traps sediment and pollutants that could otherwise contaminate surface waters and groundwater. This publication is intended for those who maintain their own lawn and landscapes.Critical Issue: 2. Water Quality, Quantity, and Supply
